Google is facing several legal challenges related to its artificial intelligence practices and data collection methods across multiple jurisdictions.

A group of independent musicians has filed a lawsuit against Google, alleging the company illegally used songs uploaded to YouTube to train its Lyria music AI model without proper authorization. The musicians claim Google considers user-uploaded music content as available for AI training purposes, though Google has not publicly acknowledged this practice.

Separately, Google has informed users of changes to its data retention policies for search interactions. The company will now save images, files, audio, and video used in searches under a new "Search Services History" setting. This includes images searched through Google Lens, recordings from real-time search features, and audio from Google Translate, with the stated purpose of improving AI training.

In Germany, a court has ruled against Google's AI Overview feature, determining that AI-powered internet search tools are unnecessary. The ruling specifically challenges Google's AI search capabilities and could have broader implications for the AI search industry.

Additionally, Google and Meta were denied requests for new trials in an ongoing case involving alleged youth social media addiction. The companies had sought to overturn previous court decisions in the case.

These legal developments highlight growing scrutiny of how technology companies collect and use data for AI development, particularly regarding user consent and the scope of permissible data usage for machine learning applications.
